Document Type and Number:
Japanese Patent JP6624241
Kind Code:
B2
Abstract:
To provide a connection structure of an electric apparatus that can prevent tips of electric wires from contacting a conductor part of a terminal board even when an electric wire differing in wire diameter, an electric wire having a collared ferrule crimped atop, etc., are inserted from an electric wire insertion opening.SOLUTION: A connection instrument for wiring comprises: an exterior member 5 which is provided with a housing space inside, and also provided with electric wire insertion openings 32a-32c for inserting electric wires into the housing space from outside; a terminal block which is formed of an electric insulator and provided with electric wire insertion spaces 25, 27 where the electric wires inserted from the electric wire insertion openings are located; a terminal board 9 which has a contact part 14 and a conductor part 13 assembled on the terminal block; elastic members 7, 8 which are assembled on the terminal block and arranged in the electric wire insertion spaces, and press the electric wires against the contact part with elastic force so as to make electric connections with the terminal board; and contact prevention parts 19a, 20a which are formed of an electric insulator, and prevent tips of the electric wires inserted from the electric wire insertion openings from coming into contact with the conductor part of the terminal board.SELECTED DRAWING: Figure 10
